Wine and Friends
One of my favorite things about wine is its ability to encourage a very communal and sharing atmosphere. Yes, the alcohol in wine can, of course, kick the social aspect of a gathering into high gear, but I'm speaking more about the inclination for wine lovers to want to share their favorite bottles with friends and family.
I have many great bottles in the "cellared" portion of my Danby 75 bottle Wine Cooler and many others that are ready in the near-term, yet I rarely open those bottles on a normal weeknight. People save bottles of wine for special occasions all the time, it's one of the main things you read about around the holidays in all of those adds for champagne and nice Napa Cabs or red Bordeaux's.
Yet I'm speaking more about the people at a particular occasion, not the "occasion," itself.
